Question

The table shows the cost of concessions at a concert. Evan spent $31.50
buying popcom for his class. How many bags of popcorn did Evan buy?

Answer 1

p= popcorn

x=number of kids in class

c= cost

Plug in data:

c = px

31.5=1.5x

Divide both sides by 1.5:

21= x

There are 21 kids in the class.
